VISIBLE PUMP Filed July 18, 1927 Patented Apr. 15, 1930 UNITED STATES PATENT OFFICE LEO DEUTSCH, OF BEAVER, 'IENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE WAYNE PUMP COMPANY, OF BALTIMORE, MARYLAND, A CORPORATION OF MARYLAND VISIBLE PUMP Application filed m 18,

This invention pertains to a fluid dispensing apparatus, and more particularly to a device adapted to selectively measure and deliver fluid from a fluid pump.

It is an object of this invention to provide a measuring device for determining amounts of fluid to be dispensed and providing said device withmeans whereby the fluid may be selectively delivered.

Another object is to provide an inexpensive, positive and desirable measuring and delivering device for dispensing fluid whereby said vfluid is dispensed through an independent recepgacle from that in which said fluid is measure Still another object is to provide means whereby delivery of a full amount of fluid is assured.

A further object is to provide a readily operable fluid measuring and control means for delivering fluid selectively to a receptacle separatefrom the measuring chamber before ultimate delivery from the device.

A still further object is to provide a dispensing apparatus of such character that the fluid is delivered from a measuring chamber to its point of delivery by gravity and by a pressure head, the delivery and measuring means being of such character that a selected amount of fluid is delivered and controlled by said measuring means.

Other, further and more specific objects will readily occur from the detailed description, specification and drawing appended hereto.

In the drawing, the figure is a fragmentary sectional elevation through the measuring chamber of a dispensing apparatus and the adjacent dispensing means. v

The dispensing apparatus illustrated is of the pump type and includes the ordinary sup port casing or standard 10 provided with the measuring chamber 11 which may be of the visible or blind type, said measuring chamber being provided with the usual top or cap 1927. Serial No. 206,675.

and suitably seated on support 12 forming 14 to the support 12', which support is provided with a suitable stufling box 15 at the top of the pot, through which a measurin pipe or tube 16 is adapted to have sliding and rotating adjustment. Fitting 17 is preferably provided at the top of the measuring tube and is suitably shaped so that there will be no tendency of the fluid to sink to an improper level, as in the case of capillary attraction, V

causing a gradual leakage over the lip ofthe measuring tube. This fitting is provided with a valve seat 18* cooperatin with the valve disc 18 for the purpose oi controlling the flow through the measuring pipe, the valve disc being controlled by a valve stem 19 actuated by suitable operating means. The overflow pipe may be controlled by any convenient means, such as the usual handle and measuring fingers (not shown) so that this measuring tube is set in proper position, measuring from the top down in the measuring chamber by a combined motion of rotation and translation, it being understood that the valve mechanism is not affected by the setting of the overflow tube and ma be separately operated in order to control t e flow of the fluid through the measuring tube after said tube has been set to deliver a predetermined amount of fluid.

A port 21 is provided in the overflow tube, said port being always located in the pct 13, having a travel from a point adjacent the draw-ofl' connections 24,23 to a point adjacent the bottom of said pot 13, which bottom is provided with stufling box 20 to prevent leakage from the pot. A suitable stuflin box 22 is also provided in the measurin tu e so that there will be communication on y to the pot '13 from the measuring chamber; that is, there will be communication past the valve 18 only to the port 21. Adjacent the top of the pot there is provided a draw-off valve 23 connected to the t by a Eipe 24, said valve controlling the ow of uid to the usual hose connections.

to a ition corresponding to the amount desired to be dispensed, and the handle is then rotated into the finger correspondin to this amount. The valve 18 is then opene by suitable mechanism 0 ting the valve stem 19,

and the valve 23 18 o ned providing access from the pot to the raw-oil hose. It will readily be a preciated that it is quite possible to so centre the valve 23 and the valve 18 so that neither maylbe operated until the handle for operating t e measuring tube is placed in a predetermined position. There will be a pressure head then due to the fluid disposed above the draw-ofl connection 24 which as well as the force of gravity will.

cause the fluid to flow down the measuring tube, throu h the rt 21 dis lacing the flui in the t 8 at t e draw-o connection 24, throug the valve 23 to the delivery hose. It will be noticed that the fitting 17 may be disposed above the support 12 in its lowermost position so it will be readily understood that any sediment in the fluid will settle on the suiiport 12 where suitable cleaning and draw- 0 communications may be provided. Also, due to the fact that the pct 13 is provided, should any sediment flow through the pipe 16 it will tend to settle in the pot where it can be suitably drained.

I do not wish to be limited to the exact embodiment of the device shown as other and various embodiments will of course be apparent to those skilled in the art.

1 claim:

1. In a device of the character described, the combination-of a measuring chamber, a fluid reservoir associated therewith, and means communicatin with said reservoir for controlling flow of uid from said chamber to saidreservoir, said means including measurin means and valve means for controlling the ow of fluid into said first named means and reservoir and a draw-ofl means from said reservoir, said valve means being 0 erable externally of said chamber and sai reservoir.

2. In a device of the character described, the combination of a measuring chamber, a fluid reservoir associated therewith and rotatable slidable adjustable means communieating with said reservoir for determining the amount of fluid discharged to said reserfrom said reservoir, said valve means being operable by means extendin through sai delivering means, and operab e externally of said chamber and said reservoir.
